Rumor: Xbox 360 Miis Comin' Up

You know this cuddly Miis that you get on the Wii? Well Xbox is taking that idea, making them more realistic, and putting them on their system. Now you can have a Mii avatar without having a Wii. It's rumored to be coming out at the end of the year.

This sounds like the first attempt by either of the two systems to incorporate Nintendo's innovative ideas that could actually turn out well. It doesn't seem to off-putting or disenchanting (like the Microsoft "Wiimote"). Thoughts?
